Patented June 1%, :WJld.

Application filed October 12, 1917. Serial No. 196,193.

To all whom it may concern:

Be it known that 1, Farmer KoNoznwsKI, a citizen of Russia, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Horseshoe-Calks, of which the following is a specification.

The primary object of the invention is the provision of a calk for horseshoes adapted for presenting both a hard and smooth roadcontacting surface, whereby the animal will be prevented from slipping and will. be enabled to obtain a firm foothold.

A further object of the invention is the provision of a horseshoe calk having a soft metal tread portion adapted for preventing slipping on smooth road surfaces, the calk however presenting a hard metal edge to the roadbed during the walking operation.

A still further object of the device is the provision of a calk for horseshoes that possesses great strength and is readily removable from the shoe, the construction being such that a hard-metal tread portion is arranged for the calk adapted for retaining in molded position therein a relatively soft metal tread portion.

In the drawings forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a bottom plan view of a horseshoe provided with four calks formed after the manner of my invention;

Fig. 2 is a side elevation of a calk arranged upon the heel portion of a shoe, the latter being shown in longitudinal section;

Fig. 3 is a similar View showing an adj acent side of the calk from that illustrated in Fig. 2 with the portion of the shoe shown in side elevation;

Fig. 4 is a transverse sectional view taken upon line IVIV of Fig. 2; and

Fig. 5 is a perspective view of a calk.

It being understood that my calk is designed for employment with any form. of horseshoe, the same is herein illustrated in connection with the shoe 10 having tapered threaded openings 11 adjacent the toe and heel portions 12 and 13 thereof respectively adapted for the reception of the threaded shank portion 14 of my device.

My calk 15 of the form best illustrated in Fig. 5 of the drawings, is H-shaped in crosssection having parallel sides 16 and a connecting wall 17 while the shank 14 which is in the shape of a truncated cone is mounted upon the closed ends 18 of the said wall and sides. The said sides 16 and wall 17 are of hollow formation and have open ends opposite their closed ends 18 while a filling 19 of relatively soft material such as lead, fills the interior of the calk and also fills a plurality of circular openings 20 in the opposite faces of the sides 16.

It will be understood that the main body portion of the calk 15 is formed of hard metal such as iron or steel and that the lead 19 is poured into the same in a molten oondition and is so arranged that the central wall 17 and sides 16 are filled with the lead for presenting an H-shaped tread surface upon the bottom of the calk, and formed of both hard and soft metal. It is understood that the soft-metal filling 19 when engaging the road will tend to prevent slipping on such surfaces as metal and asphalt and smooth stone, while a tilting of the calk 15 brings the metal side 16 in contact with the roadbed for digging into the same and assisting in the travel of the animal.

The manner of making the calk 15 as hereinbefore described, compactly unites the soft and hard metal providing a strong unitary structure that is especially serviceable when ever it is desired to prevent animals from slipping while traveling over smooth surfaces.

What I claim as new is:

A horseshoe calk comprising a hollow hard metal member of substantially H-shape in cross-section and having a plurality of perforations through the sides thereof, said hollow member being closed at one end and open at the other end, means upon the closed end for attaching the member to a horseshoe, and a soft metal body molded within said hollow member filling said perforations and having an exposed surface at the open end of the hollow member.

In testimony whereof I affix my signature.
